Differential alteration of plant functions by homologous fungal candidate effectors

Project description:<p>Rust fungi are plant pathogens that cause epidemics which threatens the production of many important plant species, such as wheat, soy, coffee and poplar. Melampsora larici-populina (Mlp) causes the poplar rust and encodes at least 1184 candidate effectors (CEs), however their functions are poorly known. In this study, we analysed the transcriptome and metabolome of Arabidopsis constitutively expressing CEs of Mlp to discover processes targeted by these fungal proteins. For this purpose, we sequenced the transcriptome and used mass spectrometry to analyse the metabolome of Arabidopsis plants expressing one of 14 selected CEs and of a control line. We found 2299 deregulated genes in at least one of the 14 transgenic lines. Among the down-regulated genes, the KEGG pathways “MAPK signaling pathway” and “Plant-pathogen interaction” were over-represented in six and five of the 14 transgenic lines, respectively. Moreover, the genes down-regulated across the fourteen transgenic lines are related to hormone response and defense. </p><p>Regarding the metabolome, there were 680 metabolites deregulated across the 14 transgenic lines, with highly unsaturated and phenolic compounds and peptides enriched among down-regulated and up-regulated metabolites, respectively, in almost all transgenic lines. Interestingly, we found that some transgenic lines expressing CEs with no similarity in amino acid sequence had similar patterns of gene and metabolite deregulation, while plants expressing CEs from the same family deregulated different genes and metabolites. Taken together, our results indicate that the sequence of effectors may not be a good predictor of its impact in the plant.</p>

Expression profiling and functional analysis of poplar WRKY23 reveals a regulatory role in defense: WRKY23-overexpressor

Project description:To investigate the function of poplar WRKY23, we generated PtWRKY23-overexpressing and -underexpressing (RNAi) plants. Transgenic plants were inoculated with Melampsora rust or mock-inoculated for assessment of rust-resistance and for gene expression profiling using the poplar Affymetrix GeneChip® to study the consequences of PtWRKY23 overexpression and underexpression. Transcriptome analysis of PtWRKY23 overexpressors revealed a significant overlap with the Melampsora-infection response. Transcriptome analysis also indicated that PtWRKY23 affects redox homeostasis and cell wall-related metabolism. Keywords: genetic modification, stress response

poplar bent study-TRANSCRIPTOMIC ANALYSIS OF POPLAR STEM ACCOMMODATION TO REPEATED BENDING Species: Populus tremula x Populus aba

Project description:affy_pop_2011_08 - poplar bent study - genes regulated by PtaZFP2 in absence of mechanical stress - genes regulated by PtaZFP2 after one bending.Species: Populus tremula x Populus alba-- The laboratory previously established a poplar transgenic line overexpressing PtaZFP2 under the control of an estradiol-inducible promoter. - the experiment, conducted on 3-month-old hydroponically-grown poplars, consists in the comparison of WT poplars treated with estradiol and the PtaZFP2-overexpressing line treated with estradiol. We also compared unbent and bent PtaZFP2-overexpressing poplars. The applied strain is quantitatively controlled (Coutand & Moulia, 2000, JExpBot; coutand et al., 2009, Plant Physiology) - 27 arrays - poplar; gene knock in (transgenic)

Genome scale transcriptome analysis of shoot organogenesis in poplar

Project description:Regeneration of transgenic cells remains a major obstacle to research and commercial deployment of transgenic plants for most species. Our aims are to improve knowledge of gene regulatory circuits important to meristem organization, and to identify regulatory genes that might be useful for improving the efficiency of regeneration during transformation. We analyzed gene expression during poplar regeneration using an Affymetrix GeneChip® array representing over 56,000 poplar transcripts. Keywords: Time course
